Cummins mpg vs 225 Slant 6 mpg

The 3/4 ton dodge gas trucks were lighter than the Cummins as well. A Cummins would turn either frame into a pretzel. In 1989 Cummins mandated the structural standards for Dodge. if Dodge didn't do it, they didn't get the engine. As mentioned earlier, the Cummins is 1300+ pounds on the nose, versus 500 or so for the slant six or the small block. Buy a real older model, and get the real deal.
